Abstract
A device for filtering treating ballast water by way of a filtering method, and more particularly, to a compact and operability-enhancing multicage-type device for filtering ballast water, which distributes a lower portion of the device for filtering a discharge portion for discharging foreign substances after backwashing a filter and a backwash line, among features that are concentrated at an upper portion of the device for filtering, and communicates discharge tubes of each filtering unit in a single line, by considering the unique installation environment of the device for filtering that is coupled to a ship, thereby simplifying structure, reducing space required for installing the device for filtering in the upper portion of the device for filtering, allowing efficient maintenance by integrating foreign substance discharge and back pressure maintenance of each of the filtering units.
